1    Convertible debentures have not been assumed converted for the fully
     diluted earnings per share as the effect would be anti-dilutive. Had the
     convertible debentures been included, the number of shares would have been
     increased by 3,450,000 to 16,658,222 and 16,719,735 for the three months
     ended September 30, 1996 and 1995, respectively.

     As a result of reduced interest expense following conversion, the increase
     to net income (or decrease to net loss) would have been $657,700 for the
     three months ended September 30, 1996 and 1995, respectively. These
     adjustments would have resulted in fully diluted earnings per share of
     $0.05 and $0.01 for the three months ended September 30, 1996 and 1995
     respectively.
